Socket-Outlet and Plug Fits 10 A, 400 V Class DC Distribution System

Mar 05, 2015

Fujitsu Component Limited obtained UL certification for its first of a kind socket-outlet and plug for a 10 A, 400 V class DC distribution system. The DC distribution system (voltage level around 400 Vdc in ICT or similar application) eliminates energy loss by DC-AC conversion and realizes highly efficient electricity distribution. In cooperation with NTT group, Fujitsu embarked early on its research and development before the rest of the world.

The DC distribution system is expected to contribute to electricity-savings and reduction of environmental load in the growing ICT field, such as transmission facilities and/or data centers. The DC distribution system has been required to ensure safe operation such as the prevention of arc discharge which occurs by current interruption and electric shock. To meet these requirements, NTT FACILITIES and Fujitsu Component jointly developed a socket-outlet and plug for 400V class DC distribution system. It has been mainly adopted in datacenters in Japan since NTT FACILITIES' promotion starting in November 2010.

The socket-outlet and plug features following multi-tier safety constructions:
